Penetrate Disguise (5e Spell)

From D&D Wiki

Within the spells duration, you have a bonus to the next Intelligence (Investigation) check you make to discern whether a creature is in a disguise. This extends to nonmagical applications such as a disguise kit or a Charisma (Deception) check; but not to magical illusions.

The bonus to your Investigation check is +5, which the DM will apply in secret after you make the roll.

In addition, you also determine if the subject is also the subject of a friends spell or other enchantment cantrip.
